2.9 Product differences
Factors to consider when replacing an existing Type 2 drive
(M81200, M81201) with a new Type 2 drive (E12207, E12208).
There are a number of important differences between the 2 drives:
• The existing Type 2 hydraulic ram (M81200, M81201) has a 5
degree tolerance of movement in the vertical plane. The new Type
2 hydraulic ram (E12207, E12208) has a 10 degree tolerance.
• For the existing Type 2 drive (M81200, M81201) the pipes that
transported the hydraulic fluid to the ram unit were connected to
the top of the unit. For the NEW Type 2 drive (E12207, E12208),
the pipes connect to the rear of the unit. You must allow at least
17 cm (6.7 in) clearance at the rear of the unit for the extruding
pipes. The minimum bend radius for the pipes is 7.6 cm (3 in).
• The new drive (E12207, E12208) can be mounted horizontally
or vertically.
• The hydraulic fluid reservoir supplied with the new drive (E12207,
E12208) is a different size and shape.
